Sonerai Wing Plans for study?
Hi Group!
I have been away so long. I am not someone any out there are familiar with. A lurker at best. I am now ready to start building my Renegade Formula V again. But, the wings are wood... Does any one have any study plans available for the Sonerai I? I would like to see what can be done for my Renegade. Metal wings would be easier for me to work with. Curtis Scholl |

Sonerai Wing Plans for study?
Several years ago a Sonerai lost a wing making a high G turn during an
air race conducted by the Formula V Air Racing Association, resulting in a fatal crash. The Formula V group then hired a professional aeronautical engineer to conduct a design study and and a wing strengthen modification was the result, which was made mandatory for all racing Sonerais. You may wish to contact the Formula V people for details : http://www.formulav.com/ Rich A. rocketeer wrote: Hi Group! I have been away so long. I am not someone any out there are familiar with.

You may wish to contact the Formula V people for details : http://www.formulav.com/ I think this post is very telling, in why you have not had any other posts answering your questions. It is a very risky procedure, to start major design modifications, or substitutions to a critical structure, like a wing. If it fails, you are probably dead. No one here is likely to be very comfortable having any part of advising, or being an accomplice of such a substitution of such magnitude and scope. So although I think it is a bit of a cliché, If you have to ask, you don't know enough to be asking. My best advise? Build it as drawn, or find a plan that has what you want, in the original design. -- Jim in NC |

Sonerai Wing Plans for study?
So although I think it is a bit of a cliché, If you have to ask, you don't know enough to be asking. Ya know something, this cliche is bit worn, tired and pulled out every time somebody asks for something different. I am aware of the very same bit of folklore. That does not keep one from trying to improve the item. I do NOT want a wood wing. If the Sonerai wing is good enough to fly in a 2 place in a normal flight mode, then it is good enough. I am NOT racing the thing, or flying an aerobatic show. I do know enough to ask. That is why I am asking. To engineer a better spar is NOT the issue. We still do not have enough information about the accident to decide if the spar failed, or the wing failed in flexure, or the guy that built it failed to insure the proper build. The engineer was not consulted to fix the issue, just to analyze the outcome of a failed wing. There are a number of formula one racers out there exchanging wings that are wood with foam and fiberglass, sheet, or other medium. Why should a Formula V aircraft be any different. And to hire an engineer to fix the issue is in the works. Thanks for asking. Curtis Scholl |

MorganS:
I stand corrected, the engineer DID come up with the modifications required to make the wing work in High stress air racing environments. The request for the source of the information is on it's way. And I will be buying the plans for the Sonerai, but not for the fuselage. After looking at Cassutt and Renegade plans for the specifications, materials and such and looking at what Ib Hansen did for his aircraft, I think I am in the correct ballpark. It is wise that the people on this newgroup not advise. I was not asking for advice from the newsgroup. Only asking for a source of study plans. And someone was kind enough to supply the name of GPASC. That is enough. Curtis Scholl Morgans wrote: "rckchp" wrote in message oups.com...
